SPECIFICATION forming part of Letters Patent No. 723,847, dated March31, 1903.

Application filed September 20,1902. Serial No. 124,216- (No model.)

To all whom it may concern.-

Be it known that I, PRISCILLA W. D0110- NEY, a citizen of the UnitedStates, residing at Columbia, in the county of Adair and State ofKentucky, have invented certain new and useful Improvements in Liftersand Conveyers for Invalids; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

This invention relates to lifters and conveyers for invalids; and theobject of it is to provide an apparatus which may be arranged to span abed and to lift-the invalid therefrom for the purpose of changing thebed or upon other occasions.

Speaking generally, the invention coinprises a supporting frameworkwhich may be so positioned as to span a bed and which has a liftingdevice with ropes attachable to a sheet-carrying frame.

Referring to the accompanying drawings, Figure 1 is a perspective Viewof the device. Fig. 2 is a plan view of the sheet-holding frame removedfrom the lifting apparatus. Fig. 3 is a detailed View of one of thesupporting straps or bands. 7

Referring specifically to the drawings, the

lifting-frame comprisesfour posts 6, which are'so placed that they willstand beside the corners of the bed, the posts on each side beingconnected at the bottom by a bracingrod 7. The head and foot posts arejoined by cross-bars 9, which are vertically adjustable, so as to spanbeds ofdifferent heights. The vertical adjustment is effected by meansof a enter slots 9, formed in the ends of the crossbars and heldtogether by hooks 9".

The standards are forked at the top to removably receive the bars 8, ofwhich there is one oneach side. These bars support a windlass devicecomprising a shaft 10, which extends across the bed and between thebars,

14, into which the hooks 13 engage.

. the forks of the posts.

10 and carries gear-wheels 10, meshing with pinions ll, on the shafts 11of which the drums ll are fixed. The shafts of the gearwheels arejournaled in the bars 8, and the drums are preferably located ontheinside of the bars, as shown. Pawl l2 and ratchet 12 serve to preventslip. Each gear-wheel operates two pinions, and each of the fourliftingropes 13 is attached to one of the drums and passes thence over asuitable pulley l3 and is provided with a hook 13 at its lower end.

The sheet-frame is formed of end bars 14 and side bars 14, whichare'joined together to form-a rectangular frame. The bars are joined atthe corners by a staple, slot, and hook, (indicated at 14 3) sothat theymay be readily separated. The side bars have eyes Firmly which shaft canbe turned by a hand-crank secured to the end and side bars are strips offabric (indicated at 14) having hooks M which engage in eyelets 15 ofthe sheet 15. A number of straps or bands 16, as indicated in Fig. 3,.may be substituted for the sheet, if desired.

The feet of the posts 6 are provided with casters 6' to facilitate themovement of the apparatus.

In operation the lifting-frame is rolled to the bed, the cross-pieces '9being placed at sufficient height to pass over the footboard. The barsof the sheet-frame are then hooked to the sheetand connectedtolthelifting-ropes. By operation of the Windlass the sheet-frame andinvalid will be lifted from the bed and may be conveyed as desired. Thebars 8 and the Windlass parts may be readily lifted from So, if desired,the side posts'may belocated on either side of the bed and thecross-bars 9 and the bars (i afterward set in place. '5

What I claim as new is 1. The combination, in an apparatus of the classdescribed, of a lifting-frame comprising posts forked at the top andconnected by vertically-adjustable cross-bars, side bars set in theforks of the posts on each side, and a Windlass device carried by eachside bar, having a crank-shaft extending across between the bars tosimultaneously operate the devices on both sides.

2. The combination, in an apparatus of the class described, of asupporting structure adapted to span a bed, and provided with a liftingdevice, and a sheet-frame comprising end and side bars detachably joinedtogether and having strips of fabric joined thereto, a

sheet, and fastening devices between the TO sheet and strips, and meansto attach the sheet-frame to the lifting device.

In testimony whereof I affix my signature in presence of two witnesses.
